Power to doorbell / transformer in wall

That would hide the cable above the skirting, but there would still be the problem of where to plug the wall-wart in (there are no sockets anywhere near by) and also getting the cable up the wall to the point where it goes into the wall.

A small transformer mounted in a pocket cut in the wall is the best bet, and I have a transformer on order. Let's see how it works.

Thanks for your help.

I don't know if you have seen them but you can get twin back boxes (not the ordinary dual type) so you could replace the existing back box & use a matching blanking plate or dummy switch to cover the second position. That would give you a neatish pocket to hide the transformer/psu:

The terminology is a bit varible between "twin" "dual " & 1+1".

Are there alternative video door bells that run on a usb or something that doesn't require a large transformer?

I'm sure older houses used to have the doorbell gubbins in the loft?

They do a PoE version of this doorbell - any chance of getting an ethernet cable to it?

Have you access to the floor void above the door?

Spur off the upstairs ring to a concealed box for the transformer and drop the 24v cable down through the ceiling and round the inside of the door to bell push position?

When I installed mine, I used bell wire essentially to run back to an 18v AC adapter that is plugging into a socket at the other end of the hallway.

I pinned the wire in place against the bottom of the coving temporarily with panel pins with the two cores flat to the bottom of the coving, and then used application of decorators caulk to adhere/cover the wire, and did the same into the corner where the wire drops down to get to the adapter.

Once I'd repainted it's 95% invisible you have to look really hard to see it.

I put one of these on the wall:

Get a 240v feed and it will output 24v, all cables hid in the wall.

Mind you I had to take the chimer out as it was doing my head in.

That's a good option, he could hide it behind the curtain

Further ferreting has come up with a Ring DIN rail transformer housing:

Add on a 24v AC transformer:

There are lots of cheaper transformers:

Update: Job now done, with a small 240v-24vDC transformer from Amazon. This one, should anyone be interested:

The plan was to enlarge the pocket in the wall to accept this as well as the Shelly relay which lives behind the switch. However, while bashing away with a hammer and chisel I discovered to my immense surprise that the wall is indeed a cavity wall, with a gap between the (thick) inner wall and outer wall. This made fitting the transformer in very easy indeed, but also opens up possibilities for insulation, which could be quite good news.

Bonus points to Sheets Tabuer and Mr Pointy for these two suggestions though. Had I been less fussy about keeping the walls clear then I'd be going with one or other of them.

Nicely done sir.

Does using a third party power supply risk any warranty claims if needed in the future?

Did you tie in the new wi-fi camera to the existing chime?

Dunno. It may, but if something stops working then I'm not planning on giving that sort of detail.

Nope. The existing doorbell and chime were battery powered and comprehensively napoo. They currently grace the bin.
